Description

La présente invention concerne un dispositif pour l'accrochage d'un balai d'essuie-glace sur un bras d'essuie-glace.The present invention relates to a device for attaching a wiper blade to a wiper arm.

Le dispositif d'accrochage du balai d'essuie-glace sur la portion d'extrémité du bras d'entraînement du balai d'essuie-glace a pour fonction d'assurer la liaison entre ces deux éléments en permettant l'articulation du balai d'essuie-glace autour d'un axe de palier d'articulation qui s'étend selon une direction généralement perpendiculaire à la direction longitudinale du balai d'essuie-glace.The function of the attachment of the wiper blade to the end portion of the drive arm of the wiper blade has the function of ensuring the connection between these two elements by allowing the articulation of the wiper blade. 'wiper around a hinge bearing axis which extends in a direction generally perpendicular to the longitudinal direction of the wiper blade.

Le document FR-A-2.659.613 décrit un dispositif d'accrochage du type comportant une pièce de montage reçue entre deux ailes latérales parallèles du balai d'essuie-glace et qui comporte deux joues longitudinales parallèles qui délimitent une ouverture supérieure oblongue pour l'introduction, en vue de son accrochage, de l'extrémité en forme de crochet du balai d'essuie-glace sur une pièce d'articulation, et du type comportant un capot d'obturation de l'ouverture après l'accrochage du balai d'essuie-glace.Document FR-A-2,659,613 describes a fastening device of the type comprising a mounting part received between two parallel lateral wings of the wiper blade and which comprises two parallel longitudinal cheeks which delimit an oblong upper opening for the introduction, for hooking, of the hook-shaped end of the wiper blade on an articulation piece, and of the type comprising a cover for closing the opening after the attachment of the blade wiper.

Dans ce document, la partie constituant la pièce de montage et la partie constituant la pièce d'articulation sont réalisées en une seule pièce ainsi que le capot d'obturation de l'ouverture qui est réalisé venu de matière avec la pièce de montage à laquelle il est relié par un film de matière plastique aminci constituant une charnière d'articulation du capot par rapport à la pièce de montage.In this document, the part constituting the mounting part and the part constituting the articulation part are made in one piece as well as the cover for closing the opening which is made integrally with the mounting part to which it is connected by a thin plastic film constituting a hinge for hinging the cover relative to the mounting part.

Cette conception est peu satisfaisante dans la mesure où la réalisation en une seule pièce du capot de fermeture ne permet pas de conférer à celui-ci des formes complexes visant notamment à améliorer l'esthétique de l'ensemble de l'essuie-glace.This design is unsatisfactory insofar as the production in a single piece of the closure cover does not make it possible to give the latter complex shapes aimed in particular at improving the aesthetics of the entire wiper.

De plus, la fragilité de la charnière est telle qu'elle limite le nombre possible d'opérations d'ouverture, puis de fermeture à nouveau, du capot, notamment en vue du remplacement du balai d'essuie-glace.In addition, the fragility of the hinge is such that it limits the possible number of operations for opening, then closing again, the hood, in particular with a view to replacing the wiper blade.

La présente invention a pour but de proposer une nouvelle conception d'un dispositif d'accrochage du type mentionné précédemment qui remédie à ces inconvénients.The object of the present invention is to propose a new design of a fastening device of the type mentioned above which overcomes these drawbacks.

Dans ce but, l'invention propose un dispositif caractérisé en ce que le capot est fixé de manière amovible sur la pièce de montage.To this end, the invention provides a device characterized in that the cover is detachably fixed on the mounting part.

D'autres caractéristiques et avantages de l'invention apparaîtront à la lecture de la description détaillée qui va suivre pour la compréhension de laquelle on se reportera aux dessins annexés dans lesquels :

  • La figure 1 est une vue en perspective éclatée illustrant les principaux composants du dispositif d'accrochage en association avec le balai d'essuie-glace et le bras d'essuie-glace ;
  • la figure 2 est une vue en section longitudinale par un plan médian qui illustre une première phase des opérations d'accrochage ; et
  • la figure 3 est une vue similaire à celle de la figure 2 qui illustre le bras d'essuie-glace en position accrochée sur le balai d'essuie-glace.
Other characteristics and advantages of the invention will appear on reading the detailed description which follows for the understanding of which reference will be made to the appended drawings in which:
  • Figure 1 is an exploded perspective view illustrating the main components of the attachment device in association with the wiper blade and the wiper arm;
  • Figure 2 is a longitudinal sectional view through a median plane which illustrates a first phase of the attachment operations; and
  • Figure 3 is a view similar to that of Figure 2 which illustrates the wiper arm in the hooked position on the wiper blade.

On a représenté à la figure 1 un balai d'essuie-glace 10 qui est pour l'essentiel constitué par deux ailes latérales parallèles 12 qui sont reliées entre elles par un dos transversal supérieur 14 de manière à conférer au balai d'essuie-glace une section transversale en forme générale de U.There is shown in Figure 1 a wiper blade 10 which is essentially constituted by two parallel side wings 12 which are interconnected by an upper transverse back 14 so as to give the wiper blade a cross section in general U shape.

Le dos supérieur 14 comporte notamment une ouverture 16 destinée à recevoir des moyens d'accrochage de l'extrémité en forme de crochet 18 de la tige 20 d'un bras d'essuie-glace 22.The upper back 14 includes in particular an opening 16 intended to receive means for hooking the hook-shaped end 18 of the rod 20 of a wiper arm 22.

A cet effet, l'ouverture 16 est délimitée latéralement par des bords supérieurs longitudinaux 24 des ailes latérales 12 et par deux bords transversaux d'extrémités 26 et 28.To this end, the opening 16 is delimited laterally by longitudinal upper edges 24 of the lateral wings 12 and by two transverse edges of ends 26 and 28.

Un axe 30 d'articulation du bras d'essuie-glace 22 sur le balai d'essuie-glace 10 s'étend transversalement entre les faces internes opposées 32 des ailes 12 du balai d'essuie-glace 10, selon une direction perpendiculaire à la direction longitudinale générale du balai d'essuie-glace 10 et du bras d'essuie-glace 22.An axis 30 of articulation of the wiper arm 22 on the wiper blade 10 extends transversely between the opposite internal faces 32 of the wings 12 of the wiper blade 10, in a direction perpendicular to the general longitudinal direction of the wiper blade 10 and of the wiper arm 22.

Le dispositif pour l'accrochage et l'articulation du bras d'essuie-glace 22 sur l'axe 30 comporte une pièce de montage 34 et une pièce d'articulation 36.The device for the attachment and articulation of the wiper arm 22 on the axis 30 comprises a mounting part 34 and an articulation part 36.

La pièce de montage 34 est pour l'essentiel constituée par deux joues latérales et parallèles 38 qui sont reliées entre elles par une paroi verticale d'extrémité 40 (voir figure 2) qui s'étend transversalement entre les joues 38 et par une tige transversale d'accrochage 42.The mounting piece 34 is essentially constituted by two lateral and parallel cheeks 38 which are connected together by a vertical end wall 40 (see FIG. 2) which extends transversely between the cheeks 38 and by a transverse rod. attachment 42.

Les joues latérales 38 sont prévues pour être reçues entre les faces internes 32 des ailes 12 du balai d'essuie-glace 10.The lateral cheeks 38 are provided to be received between the internal faces 32 of the wings 12 of the wiper blade 10.

La partie d'extrémité 44 de la pièce de montage 38 comporte un bec 46 qui, en position montée comme cela est illustré sur les figures 2 et 3, vient enserrer le bord 26 de l'ouverture 16.The end part 44 of the mounting piece 38 has a spout 46 which, in the mounted position as illustrated in FIGS. 2 and 3, encloses the edge 26 of the opening 16.

La fixation de la pièce de montage 34, outre le bec 46, est également assurée grâce à des fentes débouchantes 48 qui permettent l'emboîtement élastique des joues 38 sur l'axe d'articulation 30.The fixing of the mounting piece 34, in addition to the spout 46, is also ensured by virtue of through slots 48 which allow the elastic fitting of the cheeks 38 on the articulation axis 30.

Enfin, de part et d'autre des fentes 48, chacune des joues latérales 38 comporte une fente en arc de cercle 50 dont la fonction sera explicitée par la suite.Finally, on either side of the slots 48, each of the lateral cheeks 38 has a slot in an arc of a circle 50 whose function will be explained below.

La pièce d'articulation 36 comporte une partie centrale oblongue 52 de forme complémentaire de celle du crochet 18 du bras d'essuie-glace 22 qui est agencée entre deux bords latéraux en forme de parois parallèles 54 qui ont pour fonction de guider latéralement le crochet 18.The articulation part 36 comprises an oblong central part 52 of shape complementary to that of the hook 18 of the wiper arm 22 which is arranged between two lateral edges in the form of parallel walls 54 which have the function of guiding the hook 18 laterally.

Chacun des bords en forme de paroi 54 comporte une fente débouchante 56 qui, comme les fentes 48 des joues 38 de la pièce de montage 34 ont pour fonction de permettre l'emboîtement élastique avec articulation de la pièce d'articulation 36 sur l'axe d'articulation 30.Each of the wall-shaped edges 54 has a through slot 56 which, like the slots 48 of the cheeks 38 of the mounting piece 34 have the function of allowing the elastic interlocking with articulation of the articulation piece 36 on the axis hinge 30.

La largeur transversale de la pièce d'articulation 36 est bien entendu telle qu'elle peut être reçue entre les faces internes en vis-à-vis 39 des joues 38 de la pièce de montage 34.The transverse width of the articulation piece 36 is of course such that it can be received between the internal faces opposite 39 of the cheeks 38 of the mounting piece 34.

Chacune des faces latérales externes 56 des parois 54 de la pièce d'articulation 36 comporte deux plots en relief et opposés 58 qui, en position montée, et comme cela est illustré sur la figure 2, sont reçus dans les fentes en arc de cercle 50 de la pièce de montage 34 de manière à limiter les possibilités de pivotement de la pièce d'articulation 36 par rapport à la pièce de montage 34.Each of the external lateral faces 56 of the walls 54 of the articulation piece 36 has two raised and opposite studs 58 which, in the mounted position, and as illustrated in FIG. 2, are received in the slots in an arc of a circle 50 of the mounting piece 34 so as to limit the possibilities of pivoting of the articulation piece 36 relative to the mounting piece 34.

Conformément à l'invention, il est enfin prévu un capot 60 destiné à obturer l'ouverture 16 lorsque le bras d'essuie-glace 22 est accroché sur le balai d'essuie-glace 10 comme cela est illustré sur la figure 3.According to the invention, there is finally provided a cover 60 intended to close the opening 16 when the wiper arm 22 is hooked on the wiper blade 10 as illustrated in FIG. 3.

Dans ce mode de réalisation, le capot 60 se présente sous la forme d'une plaque dont le profil épouse celui des bords supérieurs longitudinaux 24 des ailes 12 du balai d'essuie-glace 10.In this embodiment, the cover 60 is in the form of a plate whose profile matches that of the longitudinal upper edges 24 of the wings 12 of the wiper blade 10.

En position montée, la face inférieure 62 du capot 60 prend appui sur les bords longitudinaux 64.In the mounted position, the lower face 62 of the cover 60 bears on the longitudinal edges 64.

Le capot 60 est un organe amovible qui, pour sa fixation indirecte sur le balai d'essuie-glace 10, comporte sur sa face inférieure une pince élastique ouverte 64 qui permet son accrochage par emboîtement élastique sur la tige transversale 42 de la pièce de montage 34.The cover 60 is a removable member which, for its indirect attachment to the wiper blade 10, has on its underside an open elastic clamp 64 which allows it to be hooked by elastic interlocking on the transverse rod 42 of the mounting part. 34.

En se reportant à la figure 2, et après avoir mis en place la pièce de montage 34 et la pièce d'articulation 36 dans le balai d'essuie-glace 10, on constate qu'il est possible, selon une technique connue, d'introduire le crochet 18 du bras d'essuie-glace 22 entre les joues 38 de la pièce de montage 34 puis de venir le mettre en position accrochée sur la pièce d'accrochage 36 comme cela est illustré sur la figure 3.Referring to FIG. 2, and after having put in place the mounting part 34 and the articulation part 36 in the wiper blade 10, it can be seen that it is possible, according to a known technique, to introduce the hook 18 of the wiper arm 22 between the cheeks 38 of the mounting piece 34 and then come to put it in the hooked position on the hooking piece 36 as illustrated in FIG. 3.

Il est bien entendu possible de prévoir des moyens (non représentés) pour l'accrochage du crochet 18 sur la pièce d'articulation 36 afin d'éviter tout déboîtement accidentel du crochet 18.It is of course possible to provide means (not shown) for hooking the hook 18 on the articulation piece 36 in order to avoid any accidental dislodging of the hook 18.

L'opérateur n'a plus ensuite qu'à mettre en position le capot amovible d'obturation 60, comme cela est illustré sur la figure 3, de manière à obturer l'ouverture 16 et à conférer une très bonne esthétique à l'essuie-glace. La forme du capot 60 et de la partie d'extrémité 44 de la pièce de montage 34 sont parfaitement complémentaires de la forme générale de la partie centrale du balai d'essuie-glace servant à l'accrochage du bras d'essuie-glace 22.The operator then only has to position the removable shutter cover 60, as illustrated in FIG. 3, so as to close the opening 16 and give the wipers a very good aesthetic -ice. The shape of the cover 60 and of the end part 44 of the mounting piece 34 are perfectly complementary to the general shape of the central part of the wiper blade used for hooking the wiper arm 22 .

On décrira maintenant le second mode de réalisation illustré aux figures 4 et 5 sur lesquelles des éléments identiques ou similaires à ceux décrits en référence aux figures 1 à 3 sont désignés par les mêmes chiffres de référence.We will now describe the second embodiment illustrated in FIGS. 4 and 5 in which elements identical or similar to those described in reference to Figures 1 to 3 are designated by the same reference numerals.

Comme on peut le voir sur la figure 4, la pièce de montage 34 et la pièce de liaison 36 sont initialement reliées entre elles par des parties amincies 66, susceptibles d'être ultérieurement rompues (voir figure 5) et qui, initialement, relient entre elles les joues 38 et les parois 54.As can be seen in FIG. 4, the mounting part 34 and the connecting part 36 are initially connected together by thinned parts 66, capable of being subsequently broken (see FIG. 5) and which, initially, connect between they the cheeks 38 and the walls 54.

La fixation de la pièce de montage 38 dans l'ouverture 16 est assurée par le bec 46, mais aussi au moyen de trous 68 formés dans les joues 38 et qui sont destinés à recevoir des plots 70 formés en relief, par crevé, dans les faces internes 32 des ailes 12 du balai d'essuie-glace 10.The attachment of the mounting piece 38 in the opening 16 is ensured by the spout 46, but also by means of holes 68 formed in the cheeks 38 and which are intended to receive studs 70 formed in relief, by puncture, in the internal faces 32 of the wings 12 of the wiper blade 10.

Les parois 54 de la pièce d'articulation 36 comportent chacune une rainure 72 qui est prévue pour coopérer avec un plot en relief 74 du balai d'essuie-glace 10 pour limiter les facultés de pivotement de la pièce d'articulation 36 par rapport au balai d'essuie-glace 10.The walls 54 of the articulation piece 36 each have a groove 72 which is designed to cooperate with a raised stud 74 of the wiper blade 10 to limit the pivoting properties of the articulation piece 36 relative to the wiper blade 10.

Le capot 60 d'obturation de l'ouverture 16 prend ici appui par sa face inférieure 62 sur une traverse 76 de la pièce de montage 34 qui s'étend entre les joues 38 de cette dernière.The cover 60 for closing the opening 16 is supported here by its lower face 62 on a cross member 76 of the mounting piece 34 which extends between the cheeks 38 of the latter.

Le capot comporte également une pince 64 pour sa fixation sur la tige d'accrochage 42.The cover also includes a clip 64 for fixing it to the attachment rod 42.

Dans ce mode de réalisation, les bords longitudinaux parallèles, aux faces latérales 78 du capot 60 sont reçus entre les faces internes en vis-à-vis 39 des joues 38 de la pièce de montage 34.In this embodiment, the longitudinal edges parallel to the lateral faces 78 of the cover 60 are received between the internal faces facing 39 of the cheeks 38 of the mounting piece 34.

L'assemblage des composants est identique à celui qui a été décrit en regard aux figures 1 à 3, les parties 66 étant rompues lors du premier mouvement d'articulation du bras d'essuie-glace 22 par rapport au balai 10.The assembly of the components is identical to that which has been described with reference to FIGS. 1 to 3, the parts 66 being broken during the first movement of articulation of the wiper arm 22 relative to the blade 10.
